What does vertex mean for all 3D shapes?
They are points where three or more edges meet.
How many edges meet at each vortex and does this happen to all polyhedrons?
A vortex is a form of rotating fluid flow: for example a whirlpool. A vertex, on the other hand, is a point where lines meet. There can be two or more lines meeting at a vertex: there is no limit to how many. For example, the apex of a pyramid whose base is a polygon with n-sides, will be a vertex where n edges meet (for any integer n).
How many edges of all the polyhedrons meet at each vertex?
The answer will depend on the polyhedron, but often it is 3.The answer will depend on the polyhedron, but often it is 3.The answer will depend on the polyhedron, but often it is 3.The answer will depend on the polyhedron, but often it is 3.
What is same about a cube and a cuboid?
They have 8 vertices, 12 edges and 6 faces. All edges meet at right angles. All faces meet at right angles. Every face is a rectangle (a square is a rectangle). The three vertex-to-opposite-vertex diagonals meet at a point which is the centre of gravity. This point bisects the diagonals.
what are characteristics of polyhedrons?
Polyhedrons are three-dimensional geometric shapes composed of flat polygonal faces, straight edges, and vertices. Each face of a polyhedron is a polygon, and the edges are the line segments where two faces meet. Common characteristics include having a definite volume and surface area, as well as being classified into regular (all faces are congruent) and irregular forms. Notable examples include cubes, tetrahedrons, and octahedrons.
Do all polyhedrons have 2 edges that meet at each vertex?
No. For example, a cube is a polyhedron and 3 edges meet at each vertex.

What are the properties of polyhedrons?
Polyhedrons are three-dimensional geometric shapes with flat polygonal faces, straight edges, and vertices. They are characterized by their number of faces, vertices, and edges, which are related by Euler's formula: ( V - E + F = 2 ), where ( V ) is vertices, ( E ) is edges, and ( F ) is faces. Polyhedrons can be classified into regular (Platonic solids, where all faces are identical) and irregular types. Their faces can vary in shape, but they are always formed by connecting edges at vertices.

How many edges does a retuaglaur prism have?
Try to picture a rectangular prism.An edge, first of all, is the line from a vertex to a vertex. The top has 4 edges and the bottom has 4. Then the connecting 4 edges, which is a total of 12 edges.
What three dimensional figure only contain a polygon?
...All polyhedrons
How can the vertex cover problem be reduced to the set cover problem?
The vertex cover problem can be reduced to the set cover problem by representing each vertex in the graph as a set of edges incident to that vertex. This transformation allows us to find a minimum set of sets that cover all the edges in the graph, which is equivalent to finding a minimum set of vertices that cover all the edges in the graph.
Do all polyhedrons have more edges than vertexes?
Yes. to add to that a vertex must be connected to at least 3 edges to be 3d, an edge is always connected to 2 vertexes, so the closest the two can ever be is vetexes x 3 = edges x 2, but when working with any platonic solid you can follow this: vertexes x (faces / vertexes) x [edges on one side] = edges x 2 or vertexes x [faces meeting at one vertex] = edges x 2 when working with any other polyhedron [vertexes with x amount of faces] x (x) + [vertexes with y amount of faces] x (y) ...{and so on} = edges x 2
